OpenGL Graphical Components

According to Ticket #91, the current way of displaying the
graphical sinks (oscope, fft, waterfall, etc) are all done in Python without the
use of C++ wxWidgets. There is apparently already an OpenGL version of the waterfall scope
as Ticket #86 explains. It might be worth while
to investigate getting all of these components to be written and optimized for
OpenGL.
